Specification of Letters Patent. 9

Original application filed March 29, 1912, Serial No. 687,011. Divided and this application filed November 27, 1912. Serial No. 733,766.

To all whom it may concern:

Be it known that we, GEORGES HENRI MARIUS CANTON, PIERRE GEORGES UNNii,

and EMILE J EAN SALMsoN, respectively, citizen of France, subject of the King of Sweden, and citizen of France, residing at 1 0 Lubricating Systems, of which the fo owing is a specification.

This invention relates to, a lubricating arrangement specially adapted for use in internal combustion engines of the kind comprising a number of stationary cylinders arranged radially in a vertical plane around a central rotating crank shaft arranged horizontally.

The object of the invention is to avoid sooting of the lower cylinders by excess of lubricating oil.

To this end,'the cylinders extend into the casing in such manner that the oil collected against the walls of the latter cannot pass directly into the cylinders, and a circulating cycle is created for the lubricating oil by meansof two pumps, one of which draws the oil from a reservoir and sends it to a bore in the center of the crank shaft whence the oil is projected on the moving parts through a radial passage in the crank, while the other pump draws off the excess of oil from the lower part of the central casing and forces it back'to the reservoir.

The present application is a division of our co-pending application for Letters Patent, Serial No. 687011, filed March 29th 1912.

In the annexed drawings: Figure 1 is a vertical transverse section of the engine on the line A.A of Fig. 2, Fig. 2 is a longitudinal partial vertical section on the line BB of Fig. 1.

As shown, the engine, which operates on the four-stroke cycle,comprises five stationary cylinders 1, 2, 3,4, 5, which are radlally disposed in a vertical plane. Said cylinders are'carried by a casing which is in two portions 6, 6. Iii-each of these cylinders'may levers 32, rods 30 and cams 15 equal in numher to the cylinders. As shown, the cylinders extend into the casing in such manner that the oil collected'against the walls of the latter cannot pass directly into the cylinders. I

. Twopumps 52 and 53 controlled by the engine are arranged beneath the casing. The pump 52 draws the oil contained in a reservoir 54: through the pipe 55 and sends it by way of a pipe 56 to a'distr ibuter 57 with a regulatable feed. The oil passing thence by a pipe 58 enters a passage 59 formed at the center of the shaft 10 and of the crank 10. This crank is provided with a radial passage 60 in such manner as' to project the oil in its rotation. in a plane perpendicular to the axis of rotation on all the moving parts. The excess oil passing along the walls of the casing flows into a chamber 61 arranged at the lower end of the latter and is immediately drawn off by the pump 53 which forces this oil to the reservoir 54 by way of the pipe 62. The pipe 56 leading chambered and having a radial passage leading from the chamber in the crank shaft to the surface thereof, a source of lubricant remote from the crank shaft a lubricant distributor placed above the crank shaft, a pipe for conveying lubricant from said source to the chamber in the crankshaft, a pump for forcing lubricant through said pipe, a distributing pipe connecting the lubricant distributer to the chamber in the crank shaft, a trap for excess lubricant carried near the base of the central stationary casing, and a pump for-forcing said excess lubricant back to the source.
